Evaluation of a Tdap-IPV (Tetanus, Diphteria, Pertussis and Inactivated Polio) Vaccination Remedial Strategy on Vaccination Coverage in Patients 65 Years of Age or Older (HOSPIVAC)

Evaluation of a Tdap-IPV Vaccination Remedial Strategy on Vaccination Coverage in Patients 65 Years of Age or Older in the French County of Sarthe

In France, vaccination coverage is insufficient (in 2002, 71.2% coverage for tetanus, 41.9% for poliomyelitis and 33.7% for diphteria). These numbers decrease significantly with age: coverage for people aged over 65 was 60.5%, 13.3% and 10.5% for tetanus, poliomyelitis and diphteria coverage respectively.

The primary objective of this study is to evaluate the impact of a hospital based vaccination remedial strategy for Tdap-IPV (tetanus, diphteria, pertussis and polio vaccine) in patients 65 years of age or older.

Secondary objectives are to measure the vaccination coverage of patients aged 65 years or older hospitalised in a medical ward in our hospital, to evaluate their knowledge of their vaccination coverage, and to evaluate the socio-demographic factors associated with vaccination coverage.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Intervention arm; if the patients vaccinations are up to date: no remedial vaccination is done and the patient is informed of the next remedial vaccination date; if the patients vaccinations are not up to date: remedial vaccination is realised in the unit in the absence of contraindication, in case of a temporary contraindication the vaccination will be performed on an outpatient basis by the patients primary care provider and he will be given a prescription at hospital discharge for the remedial vaccination.	Biological: Remedial vaccination; if the patients vaccinations are up to date: no remedial vaccination is done and the patient is informed of the next remedial vaccination date; if the patients vaccinations are not up to date: remedial vaccination is realised in the unit in the absence of contraindication, in case of a temporary contraindication the vaccination will be performed on an outpatient basis by the patients primary care provider and he will be given a prescription at hospital discharge for the remedial vaccination.
No Intervention: Standard care; if the patients vaccinations are up to date: no remedial vaccination is done and the patient is informed of the next remedial vaccination date; if the patients vaccinations are not up to date: the patient will be informed that a remedial vaccination is necessary and that he should contact his primary care provider after hospital discharge.
